RESUMO. Sabe-se que a casuística de gatos que apresentam sinais clínicos referentes ao trato urinário inferior (STUI) no mundo inteiro é enorme. Mas, reconhece-se também que, na maioria desses casos, não se conhece a causa específica que desencadeia tais sinais, assim como, sinais referentes a outros sistemas que por ventura venham a ser acometidos anteriormente ou concomitantemente aos STUI. O objetivo desse trabalho é investigar quais as evidências existentes atualmente sobre a cistite idiopática/intersticial felina (CIF) e como que se dá a abordagem do paciente felino para essa síndrome: quais perguntas devem ser feitas ao tutor, os achados dos exames físico e complementar, bem como os tratamentos mais indicados em cada caso em particular.Palavras chave: hematúria, gato, polaquiúria síndrome, stui Diagnosing feline idiopathic cystitis: ReviewABSTRACT. It is know that the casuistic of cats that present clinical signs referring to the lower urinary tract (STUI) worldwide is enormous. However it is also recognized that, in most of these cases, the specific cause that triggers such signals is not known, as well as signals referring to other systems that may be previously or simultaneously concomitant with STUI. The objective of this work is to investigate the current evidence on feline idiopathic / interstitial cystitis (CIF) and how to approach the feline patient for this syndrome: what questions should be asked to the tutor, the findings of the physical and complementary exams, as well as the treatments most indicated in each particular case.Keywords: hematuria, cat, polaquiuria, syndrome, luts Diagnosticando la cistitis idiopática felina: Revisión RESUMEN.

Leptospirosis is a zoonosis of worldwide distribution that has the dog as an important host, showing the importance of diagnosing and treating this animal that has a straight relationship with humans. A dog was attended at the Veterinary Hospital of the Federal University of Piauí in Teresina, Piauí, was present with history of hematuria, hyporexia and lethargy. Physical examination revealed lethargy, oral, ocular and penile icteric mucosa, pain at abdominal palpation and pyrexia. Hematologic analysis revealed hypochromic macrocytic anemia, thrombocytopenia, leukocytosis due to neutrophilia, and an increase in urea, AST, ALT, alkaline phosphatase and bilirubin values. The microscopic serum agglutination test showed a reactive result of Leptospira interrogans serovar Australis at the 1: 100 titre. The animal was effectively treated with Ampicillin, Doxycycline and supportive therapy.
